Function parse_with_unknown 

pub fn parse_with_unknown(s: &str) -> MessageList

This is like parse, except that it returns a UciMessage::UnknownMessage variant if it does not recognize the message.

/// # Examples

use vampirc_uci::{UciMessage, parse_with_unknown};

let messages = parse_with_unknown("not really a message");
assert_eq!(messages.len(), 1);
